REQUEST FOR COUNCIL ACTION <br /> Date: 5/21/2012 <br /> Item No.: 7.i <br />Department Approval City Manager Approval <br />Item Description: Award Contract for Storm Water Ditch Erosion Repair <br />B <br />ACKGROUND <br />1 <br />The drainage ditch adjacent to the Minnesota Commercial Railroad adjacent 2265 – 2285 <br />2 <br />County Road C is in need of immediate repair due to erosion of the railroad embankment. The <br />3 <br />intense rain event of July 16, 2011 washed away some of the vegetation and soils and there is a <br />4 <br />risk to the railroad tracks if we get additional intense rain events. This ditch is located in an <br />5 <br />easement on railroad property and the easement documents require us to protect the railroad <br />6 <br />embankment. <br />7 <br />City staff developed a plan in conjunction with a structural engineer to protect the railroad <br />8 <br />embankment in this area by constructing a retaining wall to absorb the turbulence as the water <br />9 <br />enters the ditch from the large diameter pipe under County Road C. Staff solicited quotations <br />10 <br />from local contractors to complete this work as soon as possible. Staff received two quotations <br />11 <br />for constructing an engineered gabion basket retaining wall per project plans. A third company, <br />12 <br />Frattalone Companies was interested, but did not submit a quotation. The following are the <br />13 <br />submitted quotations: <br />14 <br />15 <br />CompanyQuotation <br />Larson Contracting $41,280 <br />Blackstone Contractors, LLC $61,575 <br />16 <br />PO <br />OLICYBJECTIVE <br />17 <br />To maintain the structural integrity of our storm sewer system and protect private property from <br />18 <br />damage. Staff seeks to find the most cost effective purchasing opportunities to meet budgetary <br />19 <br />and operational objectives. <br />20 <br />FI <br />INANCIALMPLICATIONS <br />21 <br />This work is proposed to be funded from storm water utility capital improvement funds. <br />22 <br />S <br />TAFF RECOMMENDATION <br />23 <br />Staff recommends award of a contract to the low bidder, Larson Contracting for $41,280, to <br />24 <br />construct an engineered retaining wall to prevent further erosion of the railroad embankment. <br />25 <br />Page 1 of 2 <br /> <br />
